Infrastructure for Kubernetes: Namespaces

What are Namespaces?

Namespaces provide a mechanism for isolating groups of resources within a single Kubernetes cluster. They are commonly used to separate workloads by environment (e.g., dev, staging, prod) or by team.

In Kloudfuse, the Namespaces screen helps you monitor resource usage, deployment counts, and workload status across all namespaces. Use it to scope your observability efforts by logical boundaries within a cluster.

Access the namespaces screen

Go to Infrastructure > Kubernetes > Namespaces.

Namespace Table Columns

Each row in the table displays key namespace attributes:

• Cluster – Cluster where the namespace exists
• Namespace – Unique Kubernetes namespace name
• Status – Current state of the namespace (e.g., Active)
• Age – Time since the namespace was created
• Usage
  • CPU – Real-time CPU usage across all workloads in the namespace
  • Memory – Real-time memory usage across all workloads in the namespace
• Entity Counts
  • Pods – Total number of running pods in the namespace
  • Deployments – Number of deployments in the namespace
  • Daemon Sets – Number of daemon sets associated with the namespace
  • Stateful Sets – Number of stateful sets defined in the namespace
  • Cronjobs – Number of cronjobs scheduled within the namespace

Filters

Kloudfuse provides three categories of filters to scope your results precisely.

• Kubernetes Filter
• Facets Filter
• Additional Filter

Search, group, and sort

Use the following options to refine your search view:

1. Search

Use the Search bar to filter resources such as pods, nodes, clusters, and namespaces using key-value pairs—just like filtering logs in Kloudfuse.

• Auto-suggestions simplify input with live facet and value suggestions.
  • Example:
    1. Type cluster — autocomplete lists matching field names.
    2. Select cluster — a new dropdown appears with current cluster names.
    3. Choose one or more cluster names to apply the filter.

2. Group By

Group resources—such as Pods, Clusters, Namespaces, or Nodes—by shared attributes to simplify analysis and troubleshooting.

• Common groupings include:
  • Cluster – See how resources are distributed across clusters.
  • Namespace – Organize by logical boundaries within the cluster.
  • Node – Identify which node is hosting the resource.
  • Status – Group by lifecycle status (Running, Pending, etc.)

3. Sort

Use the sort icon to sort the list by any column in ascending or descending order.

YAML

Use the YAML tab to inspect the live configuration of your Kubernetes resource.

• View full manifest details for pods, deployments, nodes, etc.

Logs

Use the Logs tab to inspect real-time application and system logs for a selected Kubernetes resource.

Metrics

The Metrics tab displays real-time CPU, memory, network, and disk usage for the selected resource.

Events

Use the Events tab to view scheduled updates, restarts, warnings, or failed operations for a Kubernetes resource.
